Definitions
- the present invention generally relates to a carrying case and, more particularly, to a casing structure for a portable electric appliance such as, for example, a lap-top model of a personal computer, a portable word process severelyor, a portable electronic calculator or the like whose casing is designed for hand-held transportation.
- a portable electric appliance such as, for example, a lap-top model of a personal computer, a portable word process severelyor, a portable electronic calculator or the like whose casing is designed for hand-held transportation.
- the lap-top models of personal computers or the portable word processors currently available in the market comprise a generally box-like casing accommodating therein various circuit components and having a keyboard arrangement and a removable or non-removable display panel assembly.
- the display panel assembly is generally hingedly supported for movement between a closed position, in which the display panel assembly serves as a lid for concealing the keyboard arrangement for transportation, and an opened position in which the keyboard arrangement is made accessible to an operator and in which the display panel assembly is held in generally erected position with a display panel falling within the coverage of sight of the operator.
- the prior art casing of the type referred to above has two major problems; one associated with a lock mechanism for locking the display panel assembly in the closed position and the other associated with a foldable handle assembly for the hand-held transportation.
- the lock mechanism comprises a pawl member installed in one of the casing and the display panel assembly and supported for sliding motion between locked and released positions, a spring member for urging the pawl member in one direction towards the locked position and an engagement member installed in the other of the casing and the display panel assembly and engageable with the pawl member when the latter is moved towards the locked position.
- the handle assembly used in the prior art casing generally comprises a generally U-shaped handle foldably connected at its opposite free ends to the casing through hinge members.
- the use of the hinge members tends to increase the number of necessary component parts required by the casing as a whole.
- the casing is required to have a correspondingly U-shaped recess for accommodating the handle therein when the handle is in the concealed position.
- the recess for the handle generally extends inwardly of the casing and, therefore, the maximum available volume of the casing is correspondingly reduced, posing a problem in that some of the circuit component parts cannot be installed within the casing at a location in the vicinity of the recess. Therefore, the casing is required to be relatively bulky for the whole circuit component parts to be accommodated therein.
- the present invention has been devised with a view to substantially eliminating the above discussed problems inherent in the prior art carrying case for a portable electric appliance and has for its essential object to provide an improved carrying case which does not require an increased number of component parts and is therefore inexpensive to make.

- the release member is secured to the casing with set screw members inserted through perforations in the respective fitting lugs and then screwed into the wall of the casing.
- the release member is of one-piece construction made of synthetic resin including the release button, the support tongue, the pawl member, the pair of arms and the perforated fitting lugs and since the lock mechanism according to the present invention does not require the use of the separate spring such as required in the prior art carrying casing, it is clear that the carrying casing according to the present invention can be easy to fabricate at substantially reduced cost.
- a carrying of case a type which comprises a generally box-like casing accommodating therein various electric components and having a bottom opening, a bottom lid secured from below to the casing to close the bottom opening thereof and formed with a generally U-shaped pocket during the molding of the bottom lid by the use of any known plastics molding technique, and a foldable handle assembly hingedly carried by the bottom lid for pivotal movement between a concealed position, in which the handle assembly is housed within the U-shaped pocket without protruding from the bottom lid, and an exposed position in which the handle assembly is exposed outside the perimeter of the casing for the access to the hand of an operator thereto.
- the U-shaped pocket includes a pair of side grooves and a bridging groove continued to and extending between respective ends of the side grooves.

- each of the arms 23 opposite to the grip portion 24 is integrally formed with a pair of generally cylindrical bosses 25a and 25b so as to protrude laterally outwardly therefrom in coaxial relationship with each other, thereby rendering the respective arm 23 to represent a generally T-shaped configuration.
- a portion of the periphery of each of the bosses 25a and 25b is cut away to provide a flank 25a-1 or 25b-1, said flank 25a-1 or 25b-1 lying a plane inclined at a predetermined angle, for example, 20°, downwardly relative to the longitudinal axis of the associated arm 23 as viewed in Fig. 5.
- flanks 25a-1 and 15b-1 on each of the arms 23 will become clear from the subsequent description, however, briefly speaking, they cooperate with resilient retainers 36 and 37 (Figs. 5 to 7) to retain the handle 24 in the concealed position without allowing the handle 24 to arbitrarily pivot about the common longitudinal axis of the bosses 25a and 25b to separate out from the concealed position as best shown in Fig. 6.
- the bottom wall L1a of the lower cabinet CL is formed with a generally U-shaped pocket 21 opening in a direction opposite to the upper cabinet CU and positioned intermediate the width of the lap-top personal computer and in the vicinity of the front wall L1d.

Abstract
Description
- The present invention generally relates to a carrying case and, more particularly, to a casing structure for a portable electric appliance such as, for example, a lap-top model of a personal computer, a portable word processor, a portable electronic calculator or the like whose casing is designed for hand-held transportation.
- The lap-top models of personal computers or the portable word processors currently available in the market comprise a generally box-like casing accommodating therein various circuit components and having a keyboard arrangement and a removable or non-removable display panel assembly. The display panel assembly is generally hingedly supported for movement between a closed position, in which the display panel assembly serves as a lid for concealing the keyboard arrangement for transportation, and an opened position in which the keyboard arrangement is made accessible to an operator and in which the display panel assembly is held in generally erected position with a display panel falling within the coverage of sight of the operator.
- The prior art casing of the type referred to above has two major problems; one associated with a lock mechanism for locking the display panel assembly in the closed position and the other associated with a foldable handle assembly for the hand-held transportation.
- According to the prior art, the lock mechanism comprises a pawl member installed in one of the casing and the display panel assembly and supported for sliding motion between locked and released positions, a spring member for urging the pawl member in one direction towards the locked position and an engagement member installed in the other of the casing and the display panel assembly and engageable with the pawl member when the latter is moved towards the locked position.
- While the lock mechanism used in the prior art casing functions satisfactorily, it is nevertheless somewhat complicated. More specifically, the use of a biasing spring member is essential with the number of necessary component parts consequently increased and, also, the use of the spring member tends to make the assembly of the casing require an increased number of fabricating steps.
- When it comes to the handle assembly, the handle assembly used in the prior art casing generally comprises a generally U-shaped handle foldably connected at its opposite free ends to the casing through hinge members. The use of the hinge members tends to increase the number of necessary component parts required by the casing as a whole. In addition, considering the handle supported for movement between a projected position, in which the handle is exposed outside the perimeter of the casing for the access of the hand of an operator thereto, and a concealed position in which the handle is retracted inwardly of the casing, the casing is required to have a correspondingly U-shaped recess for accommodating the handle therein when the handle is in the concealed position. The recess for the handle generally extends inwardly of the casing and, therefore, the maximum available volume of the casing is correspondingly reduced, posing a problem in that some of the circuit component parts cannot be installed within the casing at a location in the vicinity of the recess. Therefore, the casing is required to be relatively bulky for the whole circuit component parts to be accommodated therein.
- Accordingly, the present invention has been devised with a view to substantially eliminating the above discussed problems inherent in the prior art carrying case for a portable electric appliance and has for its essential object to provide an improved carrying case which does not require an increased number of component parts and is therefore inexpensive to make.
- Another important object of the present invention is to provide an improved carrying case wherein the lock mechanism is simplified in structure and function with no separate spring member employed, thereby rendering the lock mechanism to be readily fabricated.
- A further important object of the present invention is to provide an improved carrying case wherein the handle assembly is simplified in structure and function with no separate hinge member employed, thereby rendering the handle assembly to be readily installed.
- To this end, according to one aspect of the present invention, there is provided a carrying case of a type which comprises a generally box-like casing accommodating therein various electric components and having a panel assembly generally hingedly supported for movement in a direction close towards and away from the casing and at least one lock mechanism operable to lock the panel assembly in position moved close to the canister.
- The lock mechanism comprises an engagement member secured to the panel assembly and a release member of onepiece construction made of synthetic resin and including a release button, a support tongue formed integrally with and extending from the release button in a direction inwardly of the canister, a pawl member integrally formed with and extending from one end of the support tongue remote from the release button in a direction generally perpendicular to the support tongue, a pair of resiliently yieldable, generally plate-like arms formed integrally with and extending from the release button in a direction away from each other and also perpendicular to the support tongue, and a perforated fitting lug formed integrally with one end of each of the resiliently yieldable arms remote from the release button and lying in a plane perpendicular to the associated resiliently yieldable arm.
- The release member is secured to the casing with set screw members inserted through perforations in the respective fitting lugs and then screwed into the wall of the casing. When and so long as the panel assembly is locked in position close to the casing with the pawl member engaged with the engagement member in the panel assembly, the application of an external pushing force to the release button results in the collapse of the release button inwardly of the casing with the arms consequently deformed against their own resiliency, thereby permitting the pawl member to disengage from the engagement member in the panel assembly.
- Since the release member is of one-piece construction made of synthetic resin including the release button, the support tongue, the pawl member, the pair of arms and the perforated fitting lugs and since the lock mechanism according to the present invention does not require the use of the separate spring such as required in the prior art carrying casing, it is clear that the carrying casing according to the present invention can be easy to fabricate at substantially reduced cost.
- In another aspect of the present invention, there is provided a carrying of case a type which comprises a generally box-like casing accommodating therein various electric components and having a bottom opening, a bottom lid secured from below to the casing to close the bottom opening thereof and formed with a generally U-shaped pocket during the molding of the bottom lid by the use of any known plastics molding technique, and a foldable handle assembly hingedly carried by the bottom lid for pivotal movement between a concealed position, in which the handle assembly is housed within the U-shaped pocket without protruding from the bottom lid, and an exposed position in which the handle assembly is exposed outside the perimeter of the casing for the access to the hand of an operator thereto.
- The U-shaped pocket includes a pair of side grooves and a bridging groove continued to and extending between respective ends of the side grooves. Opposite walls defining each of the side grooves are perforated to allow portions of the bottom lid in register with the perforations in those walls to serve as respective slide supports. That portions of the bottom lid in register with the perforations in those walls is formed with cutouts. The bottom lid is also formed, for each slide support, with a pair of stopper projections each located at one end of the associated slide support that is remote from the bridging groove, and a thin elastic plate is formed in fact-to-face relationship with each slide support.
- On the other hand, the handle assembly includes a pair of spaced arms each of said arms having one end formed into a generally T-shaped configuration with bosses protruding therefrom in a direction away from each other and perpendicular to the associated arm. This handle assembly is coupled to the bottom lid with the bosses in the arms having been inserted through the cutouts until they are engaged in between the respective pairs of the stopper projections after having slid along the respective slide supports. The handle assembly so coupled to the bottom lid is pivotable about the common longitudinal axis passing through the bosses in the arms in a controlled manner with the bosses in the arms resiliently pressed by the thin elastic plates.
- The handle assembly when in the concealed position is completely accommodated within the U-shaped pocked. However, when the operator desires to transport the electric appliance with the handle assembly held in his or her hand, he or she should pull the handle assembly in the concealed position towards the exposed position, permitting it to be pivoted about the common longitudinal axis of the bosses in the arms.

- Before the description of preferred embodiments of the present invention proceeds, it is to be noted that like parts are employed to designate like parts throughout the accompanying drawings.
- Referring first to Figs. 1 and 3, there is shown a lap-top model of a personal computer which comprises a carrying case generally identified by 1 and accommodating various electric component parts therein. The carrying case comprises generally rectangular box-like lower and upper cabinets CL and CU, each of said lower and upper cabinets CL and CU being composed of a top or bottom wall L1a or U1a, a pair of opposite side walls L1b and L1c or U1b and U1c and rear and front walls (only the front wall being designated by L1d or U1d while the rear wall is not shown) all molded together by the use of any known plastics molding technique. The lower cabinet CL has a depth smaller than that of the upper cabinet CU. The lower cabinet CL is secured from below to the upper cabinet CU so as to close a bottom opening thereof. The top wall U1a of the upper cabinet CU is stepped down with a front portion thereof held at a level lower than a rear portion thereof, and the front portion of the top wall U1a is formed with a generally rectangular opening extending alongside the front wall U1d for accommodating a
keyboard arrangement 2. Thekeyboard arrangement 2 so mounted is exposed upwardly in a direction opposite to the lower cabinet CL for the access of hands of an operator thereto. - The upper cabinet CU also has a
display panel assembly 4 hingedly supported at 5 by the upper cabinet CU for pivotal movement in a direction close towards and away from thekeyboard arrangement 2 and between folded and erected positions in a manner as indicated by the arrowheaded line. Thedisplay panel assembly 4 has a display panel 3 for the display of information processed by the electric appliance. When in the folded position, thedisplay panel assembly 4 itself completely covers and protects thekeyboard arrangement 2 substantially as shown in Fig. 3, but, when in the erected position, thedisplay panel assembly 4 permits the display panel 3 to be viewed by the operator of the lap-top personal computer as shown in Fig. 3. - The illustrated carrying case comprises two releasable lock mechanisms of identical construction for locking the
display panel assembly 4 in the folded position once it has been moved thereto. For the sake of brevity, the details of only one of the releasable lock mechanisms will now be described with particular reference to Figs. 1 and 2. - The lock mechanism comprises a generally U-shaped
engagement member 6 secured to thepanel assembly 4 and arelease member 8 of one-piece construction made of synthetic resin and including arelease button 14, asupport tongue 10 formed integrally with and extending from therelease button 14 in a direction inwardly of the upper cabinet CU, apawl member 9 integrally formed with and extending from one end of thesupport tongue 10 remote from therelease button 14 in a direction generally perpendicular to thesupport tongue 10, a pair of resiliently yieldable, generally plate-like arms 11 formed integrally with and extending from therelease button 14 in a direction away from each other and also perpendicular to thesupport tongue 10, and aperforated fitting lug 12 formed integrally with one end of each of the resilientlyyieldable arms 11 remote from therelease button 14 and lying in a plane perpendicular to the associated resilientlyyieldable arm 11. Thefitting lugs 12 haverespective fitting holes 13 defined therein for the passage therethrough of setscrew members 18. - Each of the plate-
like arms 11 lies in a plane which may be parallel to the front wall U1d when the lock mechanism is lnstalled in position as will be described later whereas each of thefitting lugs 12 integral with the respective plate-like arms 11 lies in a plane perpendicular to the adjacent plate-like arm 11 and may, when the lock mechanism is installed in position, extend in a direction inwardly of the upper cabinet UC and generally perpendicular to the front wall U1d. - As best shown therein, for each releasable lock mechanism, the front wall U1d of the upper cabinet CU has a generally
rectangular opening 15 defined therein through which therelease button 14 is exposed to the outside for the access of an operator's finger thereto, and a front edge portion of the top wall U1a of the upper cabinet CU adjacent therectangular opening 15 is formed with anaccess slot 7 through which, when thedisplay panel assembly 4 is moved to the folded position, the associatedengaging member 6 fast with thedisplay panel assembly 4 is inserted for the engagement with thepawl member 9 as will subsequently be described. - That front edge portion of the top wall U1a of the upper cabinet CU is integrally formed with a pair of generally
cylindrical posts 16 positioned interiorly of the upper cabinet U1a and on respective sides of theassociated access slot 7 and extending in a direction substantially parallel to the front wall U1d of the upper cabinet CU, each of saidcylindrical posts 16 having a free end formed with arespective screw hole 17. The spacing between thecylindrical posts 16 corresponds to the spacing between thefitting holes 13 in thefitting lugs 12 integral with therelease button 14. - The
release member 8 of each of the lock mechanism is secured from below to the upper cabinet CU with theset screw members 18 inserted through therespective holes 13 into thescrew holes 17 and then screwed firmly into the respectivecylindrical posts 16 integral with the top wall U1a. In this condition, therelease button 14 is exposed to the outside through therectangular opening 15 and thepawl member 9 is positioned immediately below theaccess slot 7. - The lock mechanism according to the present invention operates in the following manner.
- Assuming that the
display panel assembly 4 in the erected position as shown in Fig. 1 is pivoted towards the folded position, the associatedengaging member 6 fast with thedisplay panel assembly 4 enters therespective access slot 7 shortly before it is caught by the associatedpawl member 9. Theengaging member 6 entering theaccess slot 7 engages thepawl member 9, causing the latter to displace backwardly (generally clockwise as viewed in Fig. 2) to allow the further passage of theengaging member 6 in front of thepawl member 9. This is possible because there is a generally L-shaped connection between eachlug 12 and the associated plate-like arm 11 as hereinbefore detailed and because the plate-like arms 'bow' relative to thelugs 12 upon the engagement of the engagingmember 6 with thepawl member 9. When thedisplay panel assembly 4 is completely moved to the folded position, thepawl member 9 is resiliently returned to the original position while having been engaged in the engagingmember 6 in a hooked fashion. thereby locking thedisplay panel assembly 4 in the folded position. - When the
display panel assembly 4 is desired to be moved to the erected position, the operator should apply a finger pressure to eachrelease buttons 14. The application of the external finger pressure to therelease button 14 causes the latter to be retracted inwardly of the upper cabinet UC while the plate-like arms 11 are deformed against their own resiliency while substantially pivoting about theset screw members 18, resulting in the separation of thepawl member 9 away from the engagingmember 6. Removal of the finger pressure from therelease button 14 subsequent to the lifting of thedisplay panel assembly 4 allows therelease button member 14 to return to the original projected position. - From the foregoing description, it is clear that, since the plate-
like arms 11 integral with and extending away from therelease button 14 are imparted resiliency, the use of any spring member such as necessitated in the prior art lock mechanism can be advantageously eliminated. In addition, since therelease member 8 is of one-piece construction made of synthetic resin and including thepawl member 9, thearms 11, the fitting lugs 12 and therelease button 14, the number of necessary component parts for the lock mechanism and, also, the number of necessary steps required to fit the lock mechanism to the casing can be advantageously minimized. - The foldable handle assembly according to the present invention is best shown in Figs. 3 to 7. The handle assembly shown therein comprises a generally U-shaped handle generally identified by 10. The
handle 10 which may be of one-piece construction is supported for pivotal movement between concealed and projected positions, shown in Figs. 6 and 7, respectively, in a manner as will be described later and includes agrip portion 24 extending generally parallel to the front wall L1d of the lower cabinet CL and a pair of generallyflat arms 23 extending from opposite ends of thegrip portion 24 in a direction perpendicular to thegrip portion 24 and also to the front wall L1d of the lower cabinet CL. As will become clear from the subsequent description, thehandle 20 is coupled to the lower cabinet CL with any one of the opposite surfaces of each of thearms 23 lying in a plane generally parallel to the bottom wall L1a of the lower cabinet CL when and so long as thehandle 24 is held in either the concealed position or the projected position. - As best shown in Figs. 3 and 4, one end of each of the
arms 23 opposite to thegrip portion 24 is integrally formed with a pair of generallycylindrical bosses respective arm 23 to represent a generally T-shaped configuration. A portion of the periphery of each of thebosses flank 25a-1 or 25b-1, saidflank 25a-1 or 25b-1 lying a plane inclined at a predetermined angle, for example, 20°, downwardly relative to the longitudinal axis of the associatedarm 23 as viewed in Fig. 5. The function of theflanks 25a-1 and 15b-1 on each of thearms 23 will become clear from the subsequent description, however, briefly speaking, they cooperate withresilient retainers 36 and 37 (Figs. 5 to 7) to retain thehandle 24 in the concealed position without allowing thehandle 24 to arbitrarily pivot about the common longitudinal axis of thebosses - The bottom wall L1a of the lower cabinet CL is formed with a generally
U-shaped pocket 21 opening in a direction opposite to the upper cabinet CU and positioned intermediate the width of the lap-top personal computer and in the vicinity of the front wall L1d. TheU-shaped pocket 21 is composed of a widthwise groove 21b, defined at a location spaced a distance from the front wall L1d of the lower cabinet CL so as to extend parallel thereto, andparallel grooves 21a continued to the widthwise groove 21b and extending perpendicular to and between the front wall L1d and the widthwise groove 21b. The bottom wall L1a has anaccess recess 22 defined therein in communication with the widthwise groove 21b for the access of an operator's finger to thegrip portion 24 of thehandle 20 when the latter is held in the concealed position so that the operator can pull thehandle 24 out of thepocket 22 and move it to the erected position while allowing thehandle 24 to pivot about the common longitudinal axis of thebosses pocket 21 is so designed and so sized as to accommodate thehandle 24, with thegrip portion 24 and thearms 23 seated within the widthwise groove 21b and theparallel grooves 21a, respectively, when and so long as the latter is in the concealed position as shown in Fig. 6. - The bottom wall L1a of the lower cabinet CL is also formed with
slide decks arm 23, saidslide decks groove 21a to the front wall L1d and positioned on respective side of the associatedgroove 21a while having been downwardly offset relative to the bottom of the lower cabinet CL as viewed in Figs. 5 to 7. Theslide decks groove 21a are formed withrespective cutouts slide decks cut outs bosses arms 23 to pass therethrough. It is, however, to be noted that one of the cutouts, for example, thecutout 28 has a length L (Fig. 4) smaller than that of the other of the cutouts, that is, thecutout 29, so that thebosses slide decks handle 20 fitted to the lower cabinet CL with thebosses cutouts - Respective outer ends of the
slide decks 26 adjacent the front wall L1d of the lower cabinet CL are formed with tall andlow engagement projections boss 25a and, similarly, respective outer ends of theslide decks 27 adjacent the front wall L1d of the lower cabinet CL are formed with tall andlow engagement projections boss 25b.Spaces 34 between theengagement projections spaces 35 between theengagement projections bosses arms 23 of thehandle 20 so that, during the pivotal movement of thehandle 20, thebosses - Positioned interiorly of the carrying
case 1 and generally above the pairedslide decks resilient retainers handle 20 in the concealed position without allowing thehandle 20 to arbitrarily pivot about the common longitudinal axis of thebosses resilient retainers parallel grooves 21a as viewed in Fig. 3 and, as best shown in Figs. 5 to 7, extends towards the front wall L1d while lnclined downwardly so as to converge with the bottom wall L1a, it being, however, to be noted that the minimum distance between eachresilient retainer respective slide decks bosses bosses flank 25a-1 or 25b-1 and passing through the longitudinal axis of therespective boss - When the
handle 20 is to be fitted to the carryingcase 1, the bosses 15a and 15b on thearms 23 having been aligned with thecutouts cutouts handle 20 as a whole is then displaced a slight distance laterally in a direction parallel to the common longitudinal axis of thebosses bosses slide decks handle 20 after thebosses cutouts cutouts parallel grooves 21a. - Thereafter, the
handle 14 is pulled forwards, i.e., leftwards as viewed in Figs. 5 to 7, until thebosses low engagement projections slide decks spaces low engagement projections resilient retainers arms 23 to allow thebosses low engagement projections slide decks bosses spaces handle 20 between the projected position, as shown in Fig. 7, and the concealed position as shown in Fig. 6. - When and so long as the
handle 20 is in the concealed position, thehandle 20 is accommodated within theU-shaped pocket 21 with thearms 23 lying in theparallel grooves 21a and thegrip portion 24 lying in the widthwise groove 21b. However, when and so long as thehandle 20 is moved to the projected position after having been pivoted about the common longitudinal axis of thebosses arms 23 partially protrude outwards from the perimeter of the lower cabinet CL with thegrip portion 24 situated spaced apart from the front wall Lid for the access to the hand of the operator of the personal computer of lap-top model. - In this arrangement, friction is imparted at all time by the
resilient retainers bosses handle 20 is held in either one of the projected and concealed positions, thehandle 20 will not undergo any arbitrary motion because thebosses resilient retainers flanks 25a-1 and 25a-b to engage the associatedresilient retainers slide decks handle 20 in the concealed position can be readily pulled out by inserting the finger into the access recess 22 (Fig. 3) and then draw thegrip portion 24 downwards as viewed in Fig. 6. - From the foregoing description, it is clear that, since the support structure to which the
handle 20 is fitted is integrally formed with the lower cabinet CL and no other separate component are employed, not only can the number of necessary component parts be advantageously reduced, but the number of procedures necessary to fit the handle to the lower cabinet CL can also be reduced. Moreover, since the U-shaped pocket for accommodating the handle is defined in the bottom wall of the casing of the lap-top type personal computer, the handle will not interfere with the operability of the keyboard arrangement and no relatively large space is required thereby enabling a relatively increased number of electric component parts to be accommodated beneath the keyboard arrangement. - Although the present invention has been fully described in connection with the preferred embodiments thereof with reference to the accompanying drawings, it is to be noted that various changes and modifications are apparent to those skilled in the art. Such changes and mcdifications are to be understood as included within the scope of the present invention as defined by the appended claims unless they depart therefrom.
